Boston based CarbonRally offers a series of carbon reducing challenges, such as not drinking bottled water, dumping shopping bags and leaving your car at home, whereby users can compete against others to become the most carbon friendly participant. Current users include Google's offices in Boston and Pittsburgh who are openly aiming to beat one and other.
The competition is all in good fun with no prizes offered, however CarbonRally is looking at corporate sponsorship of challenges in the future.
If you're passionate about carbon emissions, CarbonRally providers a fun and friendly forum from which you can join others in saving the world.
